Name of the Vulnerable Software and Affected Versions Weekly Planner plugin for WordPress versions prior to 1.0

Description The Weekly Planner plugin for WordPress is susceptible to Stored Cross-Site Scripting through admin settings. Insufficient input sanitization and output escaping allow authenticated attackers with administrator-level permissions or higher to inject arbitrary web scripts into pages. These scripts will execute when a user accesses the injected page. This issue specifically impacts multi-site installations and those where unfiltered html has been disabled.

Recommendations Update the Weekly Planner plugin to a version newer than 1.0.
